This paper discusses the development of a digital mapping program at the Defense Mapping Agency (DMA). The evolution of a conventional mapping production program from time consuming labor intensive processes into highly interactive and versatile operations is covered. Special emphasis is placed on the rationale for implementation of enhanced hardware and software technologies into the production processes.

The Defense Mapping Agency (DMA) is developing a new technology base from which products will be produced in the 1990's. This technology will provide an automated, computer-oriented production environment that will continue to provide products that meet the users requirements. A cornerstone of this effort will be the newly structured and standardized product specifications for the 29 MK 90 baseline products. The structure concept is formed by the Feature Attribute Coding Standard (FACS). The...

In order to effectively communicate, man must have a common language. In the conventional or digital cartographic sphere, this axiom is no less true. Symbols form the language of cartography. Ideally, a worldwide standard set of symbols would solve many of the communication problems. But, this ideal solution is not technically feasible. However, within scale families of maps, standard symbology should be sought, especially in computer cartographic applications. This paper addresses the need for...

The performance of image classification techniques as applied to color cartographic maps is compared. These color maps have a lot of graininess due to imperfections in the printing process. This graininess decreases the efficiency of compression techniques. The color maps are classified using the K-means clustering algorithm and vector quantization with neighborhood classification to improve the visual quality and compression ratio. The classification is performed in various image...

Algorithms for calculating seasonal roughness lengths from digitized descriptions of surface vegetation and man-made objects are described. The 'monthly characteristic vegetation roughness' for a one square kilometer plat is a log average of 100 roughness lengths, which correspond to the vegetation codes. Seasonal histograms for each square kilometer were also computed. The concept of a roughness length due to changes in elevation is used to derive an algorithm for its calculation. Both...

The Defense Mapping Agency is a producer of raster formatted elevation data in a form called DTED (Digital Terrain Elevation Data). This data is collected from digitized source maps and from optically or digitally correlated stereopairs of photographic imagery. The various means used in producing DTED sometimes introduce a striation anomaly into the data. Conventional techniques for handling this anomaly have included the use of convolution with smoothing filters. Smoothing, however, degrades...

Data density varies greatly from one ONC sheet to another, and since the ONCs are the source for the database, it is important to consider this variation in selecting a tiling method for the DCW. Because of its ability to effectively manage large variations in data density, an adaptive, rather than a fixed, tiling scheme was believed to be the best candidate at first. It was believed that a performance improvement could be obtained through the use of regular, systematic quadtree partitions....

The problem of automatically extracting map symbology from source imagery is studied. It is concluded that a great deal of geographic knowledge used by humans, who currently perform this extraction function, must be made available to machines before the function can be automated. Several geographic knowledge sources are discussed and an attempt is made to define paradigms under which knowledge can be encoded and used in the computer. An automatic cartographic feature extraction system (ACES) is...

World Data Bank I has been reordered in such a way that the latitudes where coastlines cross meridians are sorted in order of latitude for each minute of longitude. Whether a satellite position is over sea or over land is determined by the parity of the next lower crossing. Stellar data on distance and velocity as well as direction are given in a small catalog. Boundary data for moon maria, constellations, and the Milky Way are given in a set of files. (Author)
